To all w from it may concern:

"Be it known that 'LISRAEL' PUTNAM, a citizen of the United States, residing at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in ()il Heaters; and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference being-had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon. v

My present invention relates to heating appliances and more particularly to oil stoves of the simple type used for heating poultry houses and for warming the water provided for, the fowl to prevent it from freezingin extreme weather, and it has for its object to provide an improved stove of this character embodying certain pro-visions against the danger of explosions due to accumulations of vapor from the oil fuel, while also operating to prevent accumulations of moisture, particularly water of condensation, from interfering with combustion. To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the .novel features being pointed out in the claim at the end of the specification.

In the drawings:

Figure 1 is a central vertical section through an oil heater constructed in accordance with and illustrating one embodiment of my invention.

Figure 2 is an enlarged fragmentary vertical section of the lower end of the burner tube.

Figure 3 is abottom view of the burner tube.

Figure 4 is a view similar to Figure 2, of a slightly modified construction; and

Figure 5 is a bottom view of the modified form of Figure 4:.

I have illustrated a stove or heater of known general construction embodying a closed reservoir 1 having a top 2 over which engages in telescopic relationship a cover 3, the top of which 4 is spaced above the top 2 of the reservoir, and is preferably flat so that a crock or similar drinking receptacle can be rested and maintained thereon. The side walls of the cover are provided with suitable upper and lower vents and draft openings 5 and 6. Both of the 1922. Serial N0. 559,578.

aboveparts are preferably cylindrical and a bead 7 on the lower rim of the reservoir 1 projects downwardly sufficiently to pro vide a flat bottom for the stove as a whole.

Depending from the top 2 of the reservoir, at its .center, and through which it projects, is a burner tube 8 the upper end of which is entirely open, as indicated at 9, and raised slightly above the top 2. It may be soldered in place, or, at any rate, sealed to the reservoir at this point. Within the tube is a suitably bent resilient wire yoke 10 constituting a wick holder and adapted to be inserted and withdrawn through the mouth of the tube and to maintain itself in any desired elevation to which it may be adjusted. One upwardly extending arm of the yoke, shorter than the other, is coiled or otherwise fitted as at 11, to hold the wick 12, while the other arm projects from the tube at all times and is bent to form a handle 13. The wick 12 is much smaller than the' tube in diameter and is held away from the walls thereof by the wick holder, so that the air required for combustion can pass between the wick and tube and burn the vapors issuing at the mouth of the latter, besides supplying plenty of oxygen for full combustion on the wick itself. This prevents the wick from fouling and from adhering to its tube through accumulations of carbon at the mouth of the tube. To raise or lower the wick, it is necessary only to slide the holder 10 up and down by means of the handle.

The lower end of the burner or wick tube 8 as indicated at 14 is spaced above the bot tom 15 of the reservoir and is foraminous, being pierced by a plurality of small openings indicated at 16 in Figs. 2 and 3. Also, the bottom 15 of the reservoir is preferably slightly concaved or dished. There are several reasons for this arrangement, in the practice of my invention. More or less water of condensation is generated within the burner tube 8 and descends first to the bottom of the tube and then through the opening 16 to the bottom of the reservoir, at 15, where, with the depressed bottom, it 001- lectsj in a low pool at the center. If the bottom 14 of the tube were close to this bottom 15 of the reservoir, the stove would often be rendered inoperative due to these accumulations of water freezing and sealing the lower end of the tube. If. on the other hand. the level of the body of oil indicated at 17 in Fig. 1 drops below the lower end of the burner tube, there is danger of the or explosion, due to the oily vapors that collect within the reservoir becoming ignited from the flame in the tube tom 14, which I provide, prevents such combustion on the prlnciple of a miners lamp,

while at the same time giving. am plepassage to the oil feed into the tube-and to the es cape of water of condensation originating in the tube; :1 have" found that without such an arrangement the water isuapt to,

a freeze, or otherwise clog, the-bottomv of the tube and prevent the oil from flowing. there- :In Figs; 1, 2' and 8, I haveshown the tube 8 constnucted of a single piece ,ofsheet'metal with apertures 1.6punched:the end or hottom then eof. The tube may, however, also be made as shown in Figs-.4 ando, in; which the tubular body ,portr'on fi has not a solid hotton or rend but is. covered with wine I gauze as indicated at 14land which is {held in place :by a sleeve or collar lS-on= the exterior of. the tube Themeshes oi the gauze provide theequivailent of. perforations 16 o f the other form. v

The foraminous bot-f .The stove constructed as aboye described is eperlfeotly 'safe tolleav'ewithoutattention in a poultry house forrlong periods during which it will burn continuously on one filling, "and often without more than'the most vinfrequentadjustnrients of the Wick.

The reservoir 2 is filled in the ordinary manner through a neck 21 'at one side closed by a cap ZQhaving a small vent 23' therein and oil to flow freely into the same, the bot-Q tom: oit the tube being spaced from the bot tom .o-txtherese-rvoina' wick inthe tube, and

means for supporting the wick in spaced relationship tothe walls of thetube so that an airspace isl eiit around the wick trom the mouth of the tube down *tothelevel ofthe oil therein. I l
